java - When generating beans from dtd with xjc default values are in getter methods -

i use xjc create objects dtd.

xjc -dtd mydtd.dtd -d src 

but confused default values...

in dtd file have element below:

<!element imageorder (target, format, source, output, rules?, volumename?, pvdinfo?, controls?, customize?)> <!attlist imageorder     orderid cdata #required     clientid cdata #required     priority (low | normal | high) "normal"     streamerexternal (true | false) "false"     streamerlogonid cdata #implied> 

and xjc creates object below:

@xmlaccessortype(xmlaccesstype.field) @xmltype(name = "", proporder = {     "target",     "format",     "source",     "output",     "rules",     "volumename",     "pvdinfo",     "controls",     "customize" }) @xmlrootelement(name = "imageorder") public class imageorder {      @xmlattribute(name = "orderid", required = true)     @xmljavatypeadapter(normalizedstringadapter.class)     protected string orderid;     @xmlattribute(name = "clientid", required = true)     @xmljavatypeadapter(normalizedstringadapter.class)     protected string clientid;     @xmlattribute(name = "priority")     @xmljavatypeadapter(collapsedstringadapter.class)     protected string priority;     @xmlattribute(name = "streamerexternal")     @xmljavatypeadapter(collapsedstringadapter.class)     protected string streamerexternal; . . . . .     public string getpriority() {         if (priority == null) {             return "normal";         } else {             return priority;         }     }  . . . public string getstreamerexternal() {         if (streamerexternal == null) {             return "false";         } else {             return streamerexternal;         }     } 

and want marshal new imageorder instance. when marshalling default values not set. want marshal default values. how can this.

imageorder imageorder = new imageorder(); imageorder.setorderid("orderid"); imageorder.setclientid("clientid");  jaxbcontext context = jaxbcontext.newinstance(imageorder.class); stringwriter stringwriter = new stringwriter(); marshaller marshaller = context.createmarshaller(); marshaller.setproperty(marshaller.jaxb_encoding, "utf-16"); marshaller.setproperty(marshaller.jaxb_formatted_output, true); marshaller.setproperty(marshaller.jaxb_fragment, false); marshaller.marshal(obj, stringwriter); 

expected xml:

<imageorder clientid="clientid" orderid="orderid" priority="normal" streamerexternal="false"> </imageorder> 

but this:

<imageorder clientid="clientid" orderid="orderid"> </imageorder>
